> MaterializationsRebuildLockCleanerTask never cleans the abandoned MV Rebuild
> Lock entries from MATERIALIZATION_REBUILD_LOCKS table.
> As a part MaterializationsRebuildLockCleanerTask, before clearing the entries
> it checks whether the last heartbeat time for this lock entry is lesser than
> the (current time - hive transaction timeout) but the
> MaterializationRebuildLockHeartbeater heartbeats every (hive transaction
> timeout/2) so above condition will never meet and it won't clean the entries.
